Yes, well Google's yo' friend, bro! You may also want to ask "The Doctor" who goes by here, he's the authority on Doctor Who over here. he also had the Seal of Rassilon, which he later discarded. If you ask him for permission, he'll prolly let you use his seal, but the faster option is to do a Google search. And lastly, .psd files are infinitely rare, so good luck!
